【摘要】：目的 :探讨应用超声对浅表淋巴结的良恶性进行鉴别诊断时,探头施加压力的大小对超声常用检测指标结果的影响。方法:对以浅表淋巴结肿大就诊或明确淋巴结转移住院医治的34例患者67枚淋巴结进行超声检查,分别在探头外加压力为0、3 N时对浅表淋巴结超声常用指标进行测量,结果与病理检查对照。结果:淋巴结的L/S比值以2为分界线进行计数比较,加压前后良性和恶性淋巴结计数、皮髓质厚度比例计数无差异;彩色多普勒检测淋巴结内动脉收缩期流速(PSV)、舒张期流速(EDV)差别统计学有意义;血流阻力指数RI以0.7为分界线计数,良性淋巴结计数差别有统计学意义,恶性淋巴结计数差别无统计学意义;良性淋巴结血供类型加压前后无显著差异,恶性淋巴结血供类型加压前后差异显著。结论:探头外加压力对临床浅表淋巴结超声常用指标的测量可产生重要影响,其中淋巴结内血流速度、血流阻力指数、淋巴结内血流分布规律受影响最大,因此在临床检诊中要注意探头外加压力的控制。
[Abstract]:Objective: to investigate the differential diagnosis of benign and malignant superficial lymph nodes by ultrasound. Methods: 67 lymph nodes of 34 patients with superficial lymphadenopathy or definite lymph node metastasis were examined by ultrasound. The ultrasonic parameters of superficial lymph nodes were measured when the external pressure of probe was 0 ~ 3 N, and the results were compared with pathological examination. Results: the L / S ratio of lymph nodes was counted and compared with that of 2. There was no difference in the number of benign and malignant lymph nodes before and after compression, and there was no significant difference in the proportion of cutaneous medullary thickness between the two groups. The RI of RI was 0.7 as the dividing line, the difference of benign lymph node count was statistically significant, the difference of malignant lymph node count was not statistically significant, the blood supply type of benign lymph node had no significant difference before and after compression. Conclusion: the external pressure of probe has an important effect on the measurement of common ultrasonic parameters in clinical superficial lymph nodes, including blood flow velocity and resistance index of lymph nodes. The distribution of blood flow in lymph nodes is the most affected, so we should pay attention to the control of external pressure of probe in clinical examination.
